Muroiwado abandoned quarry

Pumice stone and lava flow of a submarine volcano, ruins of a quarry

The volcanic ash that accumulated on the ocean floor during submarine volcanic activity later turned into tuff. This rock is the “Izu stone”, a prized material used for erecting the stone walls of Edo Castle in Tokyo.

Muroiwado is an abandoned quarry that was used to cut Izu Stone.

The site is now maintained for tourists, who can have a thrilling experience of walking through the tunnels and look at the interesting rocks.
